The Chiliques volcano, which hasn’t erupted in at least 10,000 years, is now showing signs of life. This pair of images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) shows the volcano in visible and nrea-infrared light (top) and thermal infrared (lower). The thermal infrared image shows hot spots in the summit crtaer caused by magma just under the surface.For more information, read: <a...

The United Kingdom was uncommonly cloud free on March 28, 2002, as can be seen in this true-color SeaWiFS image. Much of the mainland also has clear skies albeit somewhat hazy (greyish pixels), probably the result of human particulate pollution. At the very southern edge of the image a large dust cloud (brownish pixels) is visible crossing the Alboran Sea from Africa to Spain. Sensor: OrbView-2/SeaWiFS.

By precisely measuring the radiant energy emitted from Earth's surface, satellites can determine temperature at the surface-atmosphere boundary. Surface temperature influences the rate at which water evaporates, as well as wind and precipitation patterns and the formation of clouds. (Data from TIROS Operational Vertical Sounder [TOVS]) Sensor: TIROS-N/TOVS. Data Start Date: 1/1/86. Data End Date: 12/31/92.

Major dust storms are a frequent occurence over northwest Africa and the Sahara Desert. This image of a massive dust storm was aquired on February 11, 2001 by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). SeaWiFS has seen similar storms every year since its launch in August 1997.Of particular interest in this image are the eddies and waves on the lee side of the mountainous Canary Islands (center).

This dataset shows the number of people per square kilometer around the world in 1994. The data were derived from population records based on political divisions such as states, provinces, and counties. Because the resolution of the data from different nations varies, some small areas with high populations (such as Rio de Janeiro, Brazil) appear to have moderate population density spread over large areas. Sensor: No Satellite/NCGIA. Data Start Date: 12/1/94. Data End Date: 12/31/94.

Landcover classification is a description of the type of vegetation growing in an area. Different types of plants (e.g., grasses versus pine trees) reflect uniquely, giving a 'spectral signature'. Scientists use satellites to detect the spectral signature of vegetation and produce landcover classification maps from the data. Landcover classification data has applications in urban planning, natural resources management, wildlife biology, and forestry. (Data produced by the University of...

Snow and ice cover the Earth's polar regions all year round. (In this data set, snow cover data are available only for the Northern Hemisphere, which is why Antarctica appears green). At mid-latitudes, the extent of snow and ice cover varies as the seasons change. In the fall and winter months (and occasionally into spring) snowstorms lay white carpets of snow across our world's landscapes as sea surface temperatures grow cold enough to freeze lake and sea water. It is important for scientists...

Microscopic marine plants (called phytoplankton) contain chlorophyll, a green pigment they use during photosynthesis. Using satellite sensors, we can measure chlorophyll concentrations in oceans, lakes and seas to indicate the distribution and abundance of phytoplankton. Phytoplankton are the base of the marine food chain and, therefore, are a good indicator of the abundance of life in a body of water.

Cloud fraction represents the portion of sky in each pixel that is covered by clouds. Satellites can measure cloud fraction over the entire atmosphere and for all types of clouds. Since most clouds reflect incoming sunlight very well and trap heat escaping from the Earth's surface, cloud fraction is an important parameter in studies of our planet's radiant energy budget.

Researchers estimate precipitation across the entire globe by considering many different kinds of input data. Rain gauges are the most accurate, but limited to populated land areas. A variety of satellites provide complete global coverage, but they present two major challenges: First, the various satellite sensors only observe quantities related to precipitation, and algorithms must be developed to get the best estimate from each particular sensor. Second, the mix of available data is...

Colorless, odorless, and poisonous, carbon monoxide is one of the six major air pollutants regulated in the United States and in many other nations around the world. When carbon-based fuels, such as coal, wood, and oil, burn incompletely or inefficiently, they produce carbon monoxide. The gas spreads throughout the lower atmosphere (called the troposphere) from the burning of fossil fuels and vegetation.The data sets above show monthly averages of global concentrations of tropospheric carbon...

Snow and ice cover the Earth's polar regions all year round. (In this data set, snow cover data are available only for the Northern Hemisphere, which is why Antarctica appears green). At mid-latitudes, the extent of snow and ice cover varies as the seasons change. In the fall and winter months (and occasionally into spring) snowstorms lay white carpets of snow across our world's landscapes as sea surface temperatures grow cold enough to freeze lake and sea water. It is important for scientists...

Cloud fraction represents the portion of sky in each pixel that is covered by clouds. Satellites can measure cloud fraction over the entire atmosphere and for all types of clouds. Since most clouds reflect incoming sunlight very well and trap heat escaping from the Earth's surface, cloud fraction is an important parameter in studies of our planet's radiant energy budget. (Data from International Satellite Cloud Climatology Project [ISCCP]). Sensor: No Satellite/ISCCP. Data Start Date: 1/1/89....

Researchers estimate precipitation across the entire globe by considering many different kinds of input data. Rain gauges are the most accurate, but limited to populated land areas. A variety of satellites provide complete global coverage, but they present two major challenges: First, the various satellite sensors only observe quantities related to precipitation, and algorithms must be developed to get the best estimate from each particular sensor. Second, the mix of available data is...

Colorless, odorless, and poisonous, carbon monoxide is one of the six major air pollutants regulated in the United States and in many other nations around the world. When carbon-based fuels, such as coal, wood, and oil, burn incompletely or inefficiently, they produce carbon monoxide. The gas spreads throughout the lower atmosphere (called the troposphere) from the burning of fossil fuels and vegetation.The data sets above show monthly averages of global concentrations of tropospheric carbon...
